tvOS support

[RomanPodymov]

Hello.
Thank you for SPPermissions.
In this pull request I added support for tvOS. Some permissions are not supported for tvOS, that's why I made them available for iOS only with #if os(iOS). Tested it with CocoaPods.
Fixed SPPermissions.dialog example in README.

Wow! Thanks for your work!

I have not encountered development for TV, I hope you can help. Could you add a new target - example for tv in project?

Done. However I see some bugs in the example for tvOS. Would you please create a branch for tvOS support?

[ivanvorobei]

Why need new branch? Why you can't add to this branch? I don’t find fault, I just don’t understand what you want to do.

[ivanvorobei]

I think need remove for Apple TV List & Dialog controllers. Also I am try call with Native any permission - it not work (maybe need request permission only on real device?)

[RomanPodymov]

Hello @ivanvorobei
OK, I will fix all tvOS-related issues in the master branch.
Permissions are also supported by tvOS simulator, I will check why Native is not displaying in the tvOS example.

[RomanPodymov]

@ivanvorobei Left SPPermissionsDialogController and SPPermissionsListController for iOS only. Fixed the issue with tvOS example.

[ivanvorobei]

@RomanPodymov for me in tv simulator permission not requested. Maybe I do some this wrong? Simple run and tap play for request permission.

[RomanPodymov]

@ivanvorobei Fixed, check it please.

[ivanvorobei]

For now all ok! Thanks)
Let me 1-3 hours for check all changes and after it I am merge and publish new version for CocoaPods.

[ivanvorobei]

I am publish new version 5.1. @RomanPodymov many thanks for your work and time!

If anybody can help, I am add new item in Cooperation section about icon for example target.
